Powering the PRO6 system
The following details the recommended power up and power down procedures for the
PRO6 system.
Note: If you are in any doubt as to how to switch the DL3n1 units on/off, refer to their
operator manuals.
>> To power up the PRO6 system
Important Note:
DO NOT switch on the speaker sub-system until after the start-up of the PRO6
system has been completed.
After all PRO6 system interconnections have been made (refer to Figure 2 “Standard
system configuration” on page 50), start up the PRO6 system:
1 Make sure that all of the PRO6 system equipment is switched off, such as the
PRO6 Control Centre, speaker sub-system, DL351 Modular I/O unit and DL371
Audio System Engine unit.
2 Switch on the PRO6 Control Centre (see “To switch on the PRO6 Control Centre”
on page 52).
3 In the master bay of the PRO6 Control Centre, move all of the monitor and
master channel faders to the minimum position and mute all of the master
channels.
4 Power up the PRO6 components, such as the DL351 Modular I/O unit and the
DL371 Audio System Engine unit. This can be done in any order you like.
5 After the status indicator at the top of each GUI screen has
changed to green (as shown right), switch on the speaker
sub-system.
6 Switch on the audio source and start playing the audio.
7 On the PRO6 Control Centre, check that the audio inputs are routed to the master
channels. Then, unmute the master channels and gradually increase their faders
while listening to the sound levels from the speakers.
If there is no sound at all coming from the speakers when the faders are at maximum,
move the faders to below the 0dB level and check if the audio is muted somewhere
along the input paths and also check that the individual speakers are switched on. If
there is still no sound from the speakers, see “No audio” on page 73.

1 Mute the audio from the speakers and switch off the speaker sub-system.
2 Switch off the DL351 Modular I/O unit.
3 Switch off the DL371 Audio System Engine unit.
